Hawaii gpu (R9 290) and the troubles with the amd-staging-drm-next branch

Current amd-staging-drm-next branch has some issues with hawaii/CI R9 290 gpu, there is a lot of backtrace noise in the dmesg (see attachment) and some related messages during the boot. I'll add a dmesg right after the boot as well.
There are also some issues with suspend/resume which are possibly related, though not sure.
The problem appeared since the beginning of the August, IIRC. Everything was more stable previously, but it's hard to double-check older versions as long as the branch is usually force-pushed.
